`docs.no-session-narrative` reaches every durable artifact, but its detector scanned only
`docs/**/*.md` and root markdown, and nothing had ever swept the rest. The issue named four sites
from one grep and called them a floor. Deriving the population instead — a whitespace-joined sweep
over every tracked file outside the detector, for the detector's own phrasings plus the attribution
and review-round class #812 found — gave 453 sites in 108 files at `fb5592971`, and a second pass
for phrasings the first list missed (hyphenated `round-N`, "an earlier version", "the reviewer
proved") added residuals in the same files. Every site was classified with #812's three
dispositions (CUT / SEVER / KEEP with its sub-kind) under the who-benefits test; the per-site
manifests are on the PR. The rejected designs, tested-and-rejected fixtures, measurements and
traps stay; the attribution of who found them and the round in which they were found go.

The detector's population grows to `.claude/`, `.gitea/`, `.husky/` and `scripts/` regardless
of extension, minus the detector and its own test (whose fixtures ARE the phrasings) and minus
`scripts/tests/fixtures/` (test data, including decision-record copies — the same reasoning as
the records' own exemption, and what keeps the record's depth measurement true), and `--all`
lists tracked REGULAR files only — a symlink's content is its target and a gitlink has none. The #812
argument for leaving `docs/superpowers/**` in the population runs the other way here: `--diff`
sees only ADDED lines, and 287 of the 453 sites were under 30 days old — this corpus is where
narrative is being added, so the advisory nudge has reach. Density agrees: 56 line-mode hits over
the 113 regular files the predicate admits, against 9 over 66 docs files before #812. `web/` and C# stay out on the same
measurement (3 of 74 PATTERNS-matching sites, ~4,600 files). The predicate did not grow: PATTERNS
matched 74 of 453 sites, and widening the word list to the attribution class is the treadmill
the withdrawn parity test ran on. The population oracle is restated over segments with the new
arms, the synthetic cross product gains the process heads and non-markdown extensions, a fixture
witnesses that a tracked symlink is neither scanned nor counted, a `.py.bak` axis separates a
by-name exemption from a `startswith` over the same tuple, and eight mutants (drop the process
arm, drop the by-name exemption, exempt by `startswith`, drop or add a prefix, drop the fixtures
exemption, list only markdown, drop the symlink filter, test the mode per row instead of per
path) each
redden it. A pre-existing silent drop in `--diff` goes with it: git tab-terminates a `+++`
filename that contains a space, and the kept tab made `is_scanned_path` refuse the file with no
notice — fixed, with a positive control and its own mutant.

Code is unchanged by construction, measured per file type against `origin/main`: Python modules
are AST-equal with docstrings stripped, except `#` lines inside the embedded fixture programs
(string literals) of three test modules; workflows differ only in `#` lines inside `run:` block
scalars; shell, C#, TypeScript and jq are equal with comment lines stripped. The stated
exceptions: the detector and its test, 26 vitest titles that carried review-round or severity
labels or a reviewer attribution (call sites whose title changed — every changed title line
walked back to its `it(` / `it.each(...)(` anchor, so a `' + '` concatenation counts once), two
registry note strings and the mutation manifest's prose fields. scripts/tests: 1565 passed.
Web: lint, typecheck, 1319 tests green. Closes #876.

Python lint here was a property of the operator's laptop: the global instructions
say to run ruff, no workflow ran it, and with no committed config ruff fell back
to whichever ~/.config/ruff/ruff.toml the machine happened to have.

- ruff.toml at the root, pinned ruff==0.12.11 in the script-tests job.
- Both lint steps pass an EXPLICIT population from `git ls-files` with
  `--no-force-exclude`, never `ruff check .` — an `exclude` empties a
  discovery-based run into a GREEN one (top level empties both commands, [lint]
  empties check, [format] empties format --check), and `ruff check .` over zero
  files exits 0 with only a stderr warning. Guarded by an empty-population arm.
- Tree clean: 74 findings at 706674272, 57 fixed in code, 17 per-site noqa with
  reasons inline. S105 deliberately per-site, not a directory blanket. RUF100
  selected so a suppression that suppresses nothing is itself a finding.
- pyright stays ungated; reasoning in the record.

Both steps witnessed red on the runner against the shipped bodies: run 2173 job
9176 (ruff check) and run 2170 job 9163 (ruff format --check).

Docs: new record ci.python-lint-ruff-config-committed, ci.script-tests-job
cross-ref, docs/ci-cd.md (also correcting a stale ~190-tests/~10s figure to the
measured 773 tests / ~4.5 min), docs/defect-shapes-773.md §5.2 resolved.

fixes #780

Re-review caught my previous fix claiming more than it delivered. "Every unreadable input
asks" was false: validating only that `.statuses` is an array left `{"statuses":[1]}`
passing the guard, after which `.context` on a number errors and the `|| true` on the
extraction turned that error into an empty description — straight back onto the
graceful-adoption path the guard exists to distinguish from. The identical
swallow-the-error shape I had just fixed a few lines up, surviving one level deeper.

The validation domain now matches the CONSUMPTION domain: every row must be an object
with a string `.context` and a `.description` that is absent or a string. The extraction
drops its `|| true` and asks explicitly instead, since a swallowed error there is
indistinguishable from a benign "no base recorded".

Both guards are load-bearing, for DIFFERENT shapes — established by mutating them
together and separately rather than assuming the pair was redundant:

- a non-string `.description` is caught ONLY by the row validation (jq -r renders the
  object as JSON, the sed finds no `(base: …)`, and it silently reads as a legacy verdict);
- a scalar row is caught by EITHER, so with the validation weakened the extraction guard
  is what still asks.

Also noted rather than changed: this is the third read of the same status endpoint in a
worst-case hook run. Sharing one snapshot would close a narrow same-run disagreement
window, but the other two branches derive different decisions from a failed read, so
threading a shared response through them changes pre-existing logic rather than #632's.
Recorded in place so it is not rediscovered as an oversight — every `decide` exits
immediately, so the reads cannot produce one self-contradictory message.

timothy d51255a8ef fix(632): "could not check" is a third outcome, not a quiet synonym for "nothing to check"
Cold review's substantive finding. The first draft collapsed an unreadable status
response into the graceful-adoption path: `vdesc` came back empty, so `recorded_base` was
empty, so the comparison was skipped IN SILENCE — and a later, successful status read
could then auto-grant, emitting "merge gate: satisfied" for a comparison that never
happened. A transient Gitea hiccup is not evidence that the base is unchanged.

The unreadable status response and a PR with no resolvable `.base.ref` now both fall
through to a human `ask`, leaving exactly one benign silent case: a verdict that predates
#632 and could not have carried the field. The emptiness check is done in SHELL before jq
sees it, same jq-1.6 rule as the rest of this file.

Also from review: the graceful-adoption test asserted only that the decision lacked the
issue tag, so it would have passed for a base-specific ask or deny whose wording omitted
it — the failure mode most likely to appear when someone edits these messages. It now
asserts on the word "base".

Recorded rather than fixed, because fixing it would be worse: docs-only PRs exit before
this check, since that carve-out short-circuits the gate earlier. It does not auto-grant
— it passes through to an ordinary permission prompt — so the exposure is a missing
warning on a merge a human is already confirming, not a silent merge. The record now says
so instead of implying the deny is unconditional.

Mutation-verified: collapsing the unreadable case back into graceful adoption, skipping
the check on a missing live base, and dropping the mismatch deny each redden their own
test and nothing else.

timothy 00e623c066 fix(632): bind a review verdict to its BASE branch, not only to its head sha
#622 made `review-verdict/h10` a per-sha required status, so a new commit cannot
inherit an old verdict — the required context is simply absent on the new head.
Retargeting a PR's base reaches the same end from the opposite direction: the head sha
and the status both hold still while the merge-base, and therefore the effective diff
the verdict was formed against, changes underneath them. #622's record claimed the
invariant holds "by construction"; this was the documented exception, and an unrecorded
exception is how a guarantee degrades into a habit.

`post-review-verdict.sh` now records the base branch in the status description as a
trailing `(base: <ref>)`, and refuses to write a status at all if the base moved between
reading the PR and posting — the same TOCTOU window the head check already covers, which
the head check cannot see because retargeting does not move the head.
`pretooluse-merge-consent.sh` reads the field back and denies when it no longer matches
the PR's live `base.ref`.

Two choices are load-bearing, and each is pinned by a test rather than left to a comment:

- The comparator is `base.ref`, NOT `base.sha`. `base.sha` tracks the base branch's tip,
  which moves whenever anything merges to `main` — comparing it would invalidate every
  open verdict on every unrelated merge, converting a rare-event guard into a permanent
  merge deadlock. A base that merely advances is out of scope by design: rebasing onto
  it moves the head sha, which the per-sha binding already covers.
- The field goes in the status DESCRIPTION, not the verdict comment. The comment body is
  parsed by `scripts/check-review-verdict.sh`, whose grammar had three false-opens in its
  history (#629); nothing parses the description, so this adds a field without reopening
  that surface.

Scope is stated honestly rather than overclaimed: this is DETECTION on the hook path
only. A commit status carries no base of its own, so the server-side required check
cannot see a retarget, and a merge driven through the Gitea UI or API is unaffected. That
is the accepted exposure — base changes are rare, manual, and this is a two-account repo
— but it now fails loud in the one place that evaluates consent, instead of living only
in a doc.

Verdicts posted before this change carry no `(base: …)` and get NO opinion rather than a
deny; denying would block every in-flight PR the day it lands, and the window closes on
its own since verdicts are per-head and short-lived.

Verified by mutation, six mutants, each killed by its intended test: remove the hook's
deny; compare base.sha instead of base.ref; drop graceful adoption; stop recording the
base; drop the TOCTOU guard; accept a PR with no resolvable base. The positive controls
matter more than usual here — the test PR is deliberately non-docs (a docs-only PR
short-circuits the whole gate and would never reach the base check) and the rest of the
gate is unstubbed, so "the hook denied" alone proves nothing.
